Problems solved by technology

[0012] The T0PAZ model is still the LUTO model. Its shortcoming is that its common method to solve the planning and layout of urban construction land is to list several feasible schemes and analyze each scheme in order to choose a suitable scheme. However, due to the complexity of urban problems It is almost impossible to list and analyze all feasible options
[0013] Summary: It can be seen that the existing planning and layout technology of urban construction land, whether it is Nellie theory, T0PAZ model or LUTO model, has the following problems in the process of planning and layout of urban construction land: ①Technical operation is based on qualitative Master: rely on the personal experience of the planner to evaluate and analyze a few layout forms, so it is impossible to conduct a full and comprehensive analysis of all possible layout forms. There are limitations in the rationality and accuracy of the plan, and the results of its planning are often not the optimal plan for planning and layout. ③Low work efficiency: the planning process is cumbersome, and a lot of repetitive work is required in the plan comparison, which takes a long time ,low efficiency

Embodiment Construction

[0053] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0054] In the current stage of rapid urbanization, the disorderly spread of urban construction land has caused serious traffic problems, and also caused a waste of valuable land resources and construction funds. The existing urban construction land layout technology mainly relies on planners to use human brains to conduct comparative analysis of a large number of layout schemes, which has the problems of mainly technical operations, large randomness of technical results, ...

Abstract

The invention discloses an automatic layout method for urban development land. The method comprises the following steps of establishing an urban development land random distribution model by using an information processing system of which the core is a high performance computer, taking geographical data of urban areas as model input data and taking land use span pattern spots as a model processing unit, performing circulation calculation by using the random distribution model, and combining to generate all possible layout schemes of the urban development land through exhaustion; by taking road network density as a detection condition, automatically detecting the road network density of the urban development land in each layout scheme, and saving the layout scheme with the highest road network density; and automatically outputting an engineering drawing, which can be directly used by urban controllability detailed planning, by using plotting equipment. The method overcomes the defects of subjectivity and randomness generated because urban spatial layout is decided by intellectual activity of human brains in urban construction engineering practice.

Description

technical field [0001] The invention relates to an automatic layout method for urban construction land with the best road accessibility, in particular to an automatic layout method for urban construction land with the best road accessibility based on a random allocation model. Background technique [0002] The layout of urban construction land is an important link in the practice of urban planning and construction, and it is also an important technical means of urban land management. For a long time, people have made a lot of practical summaries on the layout technology of urban construction land. [0003] As early as the 1930s, Reilly conducted research on the correlation between urban construction land and the population and trade attraction range of surrounding areas based on Newton’s law of gravitation, and believed that it is directly proportional to the size of the urban population and the accessibility of the city’s traffic. . The results of this study are very close...
